CHRISTIAN F. BAOHLER, OF PHILADELPHIA, PENNSYLVANIA.

STEAM OR HOT-WATER BOILER.

To all whom it may concern.-

Be it known that I, CHRISTIAN F. BACH- LER, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Steam or Hotater Boiler, of which the following is a specification.

My invention consists of a steam or hot water boiler comprising a furnace having a water leg, and a device in the furnace connected with said leg adapted to cause a circulation of the water in said leg, said device being adapted also to form a magazine for fuel, thus subjecting said device to the products of the combustion both on the inside and outside surfaces of the same, while also acting upon the water leg, so that steam and hot water may be quickly generated.

It further consists of a baffle plate arranged over said magazine, so as to deflect the products of combustion towards the same and prevent the loss of heat-units, thus producing the best results in heating said magazine and the water leg employed.

It also consists in providing the furnace with a dome, which is adapted to admit fuel into the magazine, and to form a surface for heating sad-irons and other objects.

A further object of my invention is to provide a boiler in which each part may be readily attached to its cooperating part and the entire structure set up in a short time, forming a compact and efficient water heater and one in which any part may be quickly detached.

For the purpose of explaining my inven tion, the accompanying drawings illustrate a satisfactory reduction of the same to practice, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific arrangement and organization shown and described.

Figure 1 represents a front elevation of my steam and hot water boiler. Fig. 2 represents a side elevation thereof. Fig. 3 represents a vertical section, on an enlarged scale. Fig. 1 represents a plan view showing the baffle plate employed. Fig. 5 represents a horizontal section on line a'x, Fig. 3.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings :1 designates a base and 2 designates the ash pit of a furnace supported thereon, the ash pit having a Specification of Letters Patent.

door 3 for access thereto and the furnace provided with the grate members 4 and 5.

The body of the furnace is composed of the exterior jacket or shell 6 and the interior casing or shell 7, leaving between them the water leg 8, said jacket having inlet and outlet nipples 9 and 10 for evident purposes of supplying water to said leg and directing steam or hot water therefrom.

In the upper part of the combustion chamber 11 of the furnace, is the coil 12, whose ends are connected at opposite places 13 with {he casing 7 and communicate with the water Surmounted on the body of the furnace, is the dome 1 1, which is composed of members 15 and 16, detachably connected by the bolts 17 and having in the top member an opening 18, which is adapted to be closed by the cap or lid 19, the upper surface of said member being adapted to form a heating medium for sad-irons or other objects placed thereon. Below said lid 19 is the lid 20, which occupies the opening 21 in the baffle plate 22, which is sup orted on the top closing wall of the body of t 1e furnace and secured thereto by the bolts 23, Said plate being inclined or deflected downwardly, as at 24, toward the top of the coil 12 said opening having a surrounding depending flange over the coil. I11 said plate is an opening 25, through which the products of combustion pass from the furnace to the exit collar 26.

The furnace is provided with a side-door 27, so as, if desired, to be supplied with fuel in the usual manner.

It will be seen that the interior coil 12 produces a large heating surface for the water, as does also the water leg 8.

When the lids 19 and are removed, fuel may be poured into the coil, the latter thus acting as a self-feeding magazine, whereby the coil is subjected to heat which rises from the burning fuel and acts on both of what may be termed the inner and outer surfaces of the coil, the water leg being also subjected to the heat, and thus the steam and hot water may be quickly generated, while the water rapidly circulates through the leg and coil.

The boiler as such is of inexpensive, compact and durable construction.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a boiler, a furnace having a body composed of inner and outer walls forming awater leg and a combustion chamber, a coil supported near the upper end of said chamber and connected at opposite ends with said water leg, a baffle plate supported upon the upper ends of said walls with an opening disposed over said coil, a closure therefor, and a dome supported on the upper ends of said walls, said dome being formed ofaplurality of detachably connected members, the upper member having a closure removed from and in line with the closure of said baffie plate.

2. In a boiler, a furnace having a body composed of inner and outer walls forming a water leg and a combustion chamber, a coil supported near the upper end of said cham ber and connected at opposite ends with said water leg, a baffle plate supported upon the upper end of said inner wall and inclined downward toward said coil and provided with an opening, and a removable closure for said opening.

3. In .a boiler, a furnace having a body composed of inner and outer walls forming a water leg and a combustion chamber, a coil supported near the upper end of said cham ber and connected at opposite ends with said water leg, a baffle plate supported upon the upper end of said inner wall and inclined downward toward said coil and provided with an opening, a removable closure for said opening, said baffle plate having an opening out of the plane 'of the coil, and a dome supported above the baflle plate and having an outlet through which the products of combustion pass.

4. In a boiler, a furnace having a body with inner and outer walls forming a water leg and combustion chamber, a coil having connections at its upper and lower ends with said water leg, a baffle plate at the upper end of said body and having an opening over the coil, a removable closure for said opening, a

dome secured to said body and comprising of said body and having an opening over the coil, a removable closure for said opening, a dome secured to said body and comprising detachably united members, the outer member having an opening in vertical alinement with the opening in the baffle plate, and a removable closure for said opening, said members having a lateral outlet and a baffle plate having an opening at one side of its center for the passage of the products of combustion.

6. In a boiler, a furnace having a body with inner and outer walls forming a water leg and combustion chamber, a coil having connections at the upper end of said body and having an opening over the coil, a removable closure for said opening, a dome secured to said body and comprising detachably united members, the outer member having an opening in vertical alinement with the opening inthe baffle plate, and a removable closure for said opening, said members having a lateral outlet and a baffle plate having an opening at one side of its center for the passage ofthe products of combustion, said baffle plate being inclined downwardly toward its center and having a depending flange adjacent to the coil.
